Summary
A new AI chatbot helps construction site managers access building information quickly. This conversational AI improves efficiency and usability for essential construction data retrieval.
Area of Science:
- Construction Management
- Artificial Intelligence
- Human-Computer Interaction
Background:
- Recent labor shortages and the global pandemic highlighted the need for efficient digital tools in construction.
- Traditional software is often inconvenient for mobile construction workers, hindering adoption.
- Conversational AI offers an intuitive interface to improve system usability.
Purpose of the Study:
- To develop an AI-based chatbot for construction site managers.
- To enable efficient retrieval of building component dimensions via natural language queries.
- To address the limitations of traditional form-based software in dynamic site environments.
Main Methods:
- Development of a demonstrative Natural Language Understanding (NLU) model.
- Prototyping an AI chatbot integrated with Building Information Modeling (BIM) techniques.
- Implementation of a chatbot answering module utilizing BIM data.
Main Results:
- The AI chatbot demonstrated successful intent and entity prediction for site manager inquiries.
- Satisfactory accuracy was achieved in both intent recognition and information retrieval.
- The system provides a viable alternative for accessing critical construction data.
Conclusions:
- The developed AI chatbot offers an efficient and user-friendly solution for construction site managers.
- Conversational AI integrated with BIM can significantly enhance information access on construction sites.

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

01:27Manufacture of Concrete Masonry Units
142
The process of manufacturing concrete masonry units begins by mixing stiff concrete composed of Portland cement, aggregates, and water. This mixture is then poured into metal molds. To ensure the concrete settles uniformly and to avoid separation of its components, the mixture in the molds is subjected to vibration. Shortly after, the still-wet blocks are removed from the molds and placed on racks.
These wet blocks are then transported for curing, which can occur in one of two environments: a...

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

1.2K
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.
